Server configuration

Operating system: docker dev setup

Web server: apache

Database: mysql

PHP version: 8.1

Nextcloud version: master

Group folders version: master

Reproduce the collision by creating folder 'A' and a group folder named 'A' in the reported Docker setup. Start by reading apps-extra/groupfolders/lib/Mount/MountProvider.php around lines 107 and 122, then follow the move operation into lib/private/Files/Cache/Cache.php around line 627. Done means the collision is handled without the reported failure when loading the Files app.
